Specification of Letters Patent.

Patented July 15, 1919.

Application filed November 9, 1918. Serial No. 261,810.

To all whom it may concern Be it known that I, NATHAN RooDMAN, a citizen of Russia, residing in the borough of Manhattan, in the city, county, and State of New York, have invented certain new and useful Improvements in Bracelets, of which the following is a specification, reference being had therein to the accompanying drawings, which form a part thereof.

My invention relates to bracelets, and more particularly to a type thereof known as flexible block bracelets composed of a sequence of units pivotally connected in a manner to impart to the structure the desired flexibility to permit it to conform to the forearm when being donned by the wearer.

Bracelets of the character to which my invention relates are ordinarily made in. precious metal, such as gold or platinum, the several units or blocks either being artistically finished as by chasing or'engraving, or by having jewels mounted therein, or made up of both characters of blocks.

\Vhen working in precious metals, it is not only necessary to secure excellence in the workmanship and finish of such bracelets, but it is highly desirable to so construct and assemble the various blocks as to economize the material entering thereinto, without sacrificing the strength of the structure to an extent which may result in the separation of the different blocks and a possible resulting loss of the bracelet.

WVith these conditions in mind, I have constructed a. bracelet wherein all of the blocks excepting those at the ends carrying the catch mechanism, are of the same construction, these blocks being joined together in a manner to secure the necessary degree of flexibility to permit the bracelet to assume an elliptical form. The structure of the hinge connection between adjoining blocks is such as to permit the convenient assembling of each block and the rapid and convenient assembly of different blocks to form the completed structure. The different parts entering into each block are so constructed as to facilitate a permanent joinder of these parts in a relation which will permit the proper fitting of the different blocks entering into the bracelet when assembling the same therein.

The invention consists primarily in a bracelet formed of a plurality of blocks each composed of a channeled member, a hinge socket piece having a transversely extending opening therein, carried by, and projecting beyond the end of said channeled member, said channeled member having at the other end of the side flanges thereof, openings adapted to register with the openings in the hinge socket piece of the adjoining member, and a hinge pin passing through the openings in said side flanges and through said hinge socket piece, whereby said blocks are flexibly connected, and in such other novel features of construction and combination of parts, as are hereinafter set forth and (lo-- scribed, and more particularly pointed out in the claims hereto appended.

Referring to the drawings,

Figure 1 is a perspective view of a bracelet made in accordance with my invention;

Fig. 2 is an enlarged perspective view of one form of block;

Fig. 3 is a view similar to Fig. 2 of another form of block; and

Fig. 4 is a perspective view of a modified form of socket piece.

Like letters refer to like parts throughout the several views.

In the embodiment of my invention shown in the drawings, I have illustrated a flexible block bracelet formed of a plurality of pivotally connected units, each comprising a block a of channeled material having substantially parallel ends, one end of said block havin soldered, or otherwise secured therein, a liinge socket piece 6 having a transversely extending elongated opening therein, the elongation of said opening being longitudinally of said block. This hinge socket piece in the form of the invention illustrated in Fig. 2, is formed of a flattened metal tube of the same material as the block a, and includes therein a flattened portion 1) adapted to seat upon the bottom of the channel in order to secure accuracy in the positioning of the piece, and to facilitate the assembling of said piece in relation to said block. The flattened portion Z) is preferably a small plate soldered to the tubular portion of the hinge piece.

Said hinge piece I) and the flattened portion 1) thereof, have a close fit with the side flanges of the block a, and the tubular portion thereof projects beyond the end of said block, so that in assembling a number of blocks in a completed bracelet, this projected portion of the hinge piece Z) Will enter between the flanges of the adjoining block, and

thus secure substantial continuity in theouter face of the bracelet. The side flanges a at the end thereof opposite the hinge piece Z2, have alined openings a therein,

adapted to register with theopening inthe projected portion of the hingepiece b of the adjoining block.

Adjoining blocks a are pivotallycon-- nected by means of hinge pins- 0 having; a close driving. fit in the opening a and a loose fit in the opening in the hingepiece b. This loose fit between the hinge. pin cand the opening in the hinge socket piece, permits that. slight relative movement of adjoining blocks necessary to permit the de--' sired curvature of the completed bracelet in its entirety, the adjoining-blocksseparating slightly as the bracelet takes form, and

the edges of the side flanges 64' within the bracelet ultimately abutting so as to. limit the amount ofpivotal movement of said blocks. By this construction the degree of. flexibility of the bracelet is limitedto that necessary to give it form while in use,xthe curved structure, when theends arexunited, being substantially rigid, or suflieiently= so to prevent the-collapsingof the bracelet, or its losing the elliptical forindesired.

In the form ofthe invention shown inFig. 3, the structure of theblock a is as-heretofore described, the sole difference-being that the hinge piece instead of: being. formed of substantially elliptical tubular stock, is formed of a plate d havingza close fit: between the side flanges-a of the block a, and

adapted to be solderedthereto, onesedge of: the plate (Z seating upon thecbottom of'the.

channel of saidblocln Secured to the outer face of the plate (Z is a looped portion d projecting beyond the. end of the block a and forming. a hinge. socket: adapted to. re-

" V ceive the, pin 0 of'an adjoiningblock. This struction of thehinge socket piece, and' inv that the amount of material entering into this form of a:socket piece is slightly less than that used. in the form shown in F ig.2.v

In the form of the invention showir in form of the invention. differs from that: shown in Fig. 25 merely in:the detailed'ooiu Fig. 4:, the construction is the same. as that shown in Fig. 3,.withthe'eXception that instead of. usinga continuous loop suchasd, I employ two short loops ee-, secured to a plate 6 similar to theplate d. The solev advantage of the form. of the invention shown in Fig. 4 is thatthe bulkof metal required' in the. hinge piece isreduced to a minimum, without: materially: sacrificing. the strength of. thebracelet. I f 7 Where precious metals are employed, the,

saving. of material'isa matter of consider: able mportance, 1t belng equally important, however, to secure suflicient strength blocks;

in the completed product to minimize the likelihood of breakage thereof underordinary conditions of use.

The blocks a may be decorated in any desired manner, the form of the invention appurtenances are concerned, each block is a. duplicate of every other, the construction being such that the various unitsen'tering into a bracelet may be assembled. Without any nicetyin the fitting. of parts, or in the adjustmentofone unitinrelation to the ad joining unit. If itbe found that suflieient flexibility isnot secured, this may be remedied. by touching the ends of the-block a with afile, to increase the quantity of movement ofv adjoining blocks with relation to each other, although ordinarilythe play between the. hinge pin 0 andlthe hinge socket piece 6 (l -p01 ee" is suflicient to permit that small? separation of adjoining. blocks, necessary to permitv the desired small relative pivotal movement. 7

A bracelet made in accordance with my lnvention is assembled in the form of a straigl'rt stripofa length to secure the 'desired size, one endblock thereof being pro;

vided With a keeper. 'of the ordinary construction, cooperating'witha catch member carried by the otherend block, such a catch being. indicated at: in Fig. l oftheaccompanylng. drawings;- r

The various blocks, hinge socket pieces,

and pivot pins, are preferably all made of.

the. same. metal, the ends of the pins a pro de fiangesa, being out, I Off find the :ends thereof finished in am anner jectingbeyond the s to A prevent any unsightlinessresulting: from.

the manner of assembling. the various Of course the material of the vari-1 ous blocks is notmaterial to the invention, although 1n practice the structure of'm'y in vention isordinarily used'lonly' in bracelets formed of articles. 7 The construction of each block is' such gold: or platinum, or high grade; I

12 0 that. the hinge socket piece at one end thereof: may be readily secured in place by being soldered. to the. channeled member,

without likelihood: of thesolder entering the pivot opening; in said hinge piece.-

. Furthermore, the channeled member and-Pthe hinge piece may be readily handled when V soldering: 1

Inadditionto a substantialsav-ing of the 1' 1 3 0 material entering into each block, I am enabled, in a bracelet made in accordance with my invention, to produce each block with a substantial saving of labor, and yet re tain in a completed bracelet, an intrinsic value measured by that of the precious metal embodied therein. In other Words, a bracelet made in accordance with my invention, possesses all of the artistic and intrinsic values of flexible block bracelets wherein the structure of the blocks difi'ers from that of the blocks embodied in my invention, and in addition thereto, such a bracelet possesses greater uniformity of structure throughout, can be more conveniently produced, and possesses the same, or greater, strength than other forms of bracelets of the same general character.

It is not my intention to limit the invention to the decorative characteristics of the bracelet, nor to other details of construction shown in the accompanying drawings, it being apparent that such may be varied without departing from the spirit and scope of the invention.

Having described the invention, what I claim as new and desire to have protected by Letters Patent, is:-
